pkgbuild 1.4.5

pkgbuild now does a better job at finding Rtools 4.3 and 4.4 if they were not installed from an installer.
pkgbuild now detects Rtools correctly from the Windows registry again for Rtools 4.3 and 4.4

pkgbuild 1.4.4

Running bootstrap.R now works with pkgbuild_process, so it also works from pak (https://github.com/r-lib/pak/issues/508).

New Config/build/extra-sources DESCRIPTION option to make pkgbuild aware of extra source files to consider in needs_compile().
New Config/build/bootstrap DESCRIPTION option. Set it to TRUE to run Rscript bootstrap.R in the package root prior to building the source package (#157, @paleolimbot).
pkgbuild now supports Rtools43.
pkgbuild now always appends its extra compiler flags to the ones that already exist in the system and/or user Makevars files (#156).

pkgbuild can now avoid copying large package directories when building a source package. See the PKG_BUILD_COPY_METHOD environment variable in ?build or the package README (#59).

This is currently an experimental feature, and feedback is appreciated.
R CMD build warnings can now be turned into errors, by setting the pkg.build_stop_for_warnings option to TRUE or by setting the PKG_BUILD_STOP_FOR_WARNINGS environment variable to true (#114).
need_compile() now knows about Rust source code files, i.e. Cargo.toml and *.rs (#115).
Now pkgbuild::build() will not clean up inst/doc by default if the Config/build/clean-inst-doc entry in DESCRIPTION is set to FALSE (#128).
New PKG_BUILD_COLOR_DIAGNOSTICS environment variable to opt out from colored compiler output (#141).
pkgbuild now works with a full XCode installation if the XCode Command Line Tools are not installed, on macOS, in RStudio (#103).

Accept Rtools40 for R 4.2, it works well, as long as the PATH includes both ${RTOOLS40_HOME}/usr/bin and ${RTOOLS40_HOME}/ucrt64/bin. E.g. ~/.Renviron should contain now
```
PATH="${RTOOLS40_HOME}\usr\bin;${RTOOLS40_HOME}\ucrt64\bin;${PATH}"
```
to make Rtools40 work with both R 4.2.x (devel currently) and R 4.1.x and R 4.0.x.

pkgbuild now supports Rtools 4.2.
pkgbuild now returns the correct path for R 3.x (#96).
build() now always returns the path of the built package (#108).
pkgbuild output now looks better in .Rmd documents and in general in non-dynamic terminals. You can also force dynamic and non-dynamic output now (#64).
pkgbuild does not build the PDF manual now if pdflatex is not installed, even if manual = TRUE (#123).

Gábor Csárdi is now the maintainer.
build_setup_source now considers both command-line build arguments, as well as parameters vignettes or manual when conditionally executing flag-dependent behaviors (@dgkf, #120)

pkgbuild is now licensed as MIT (#106)
compile_dll() gains a debug argument for more control over the compile options used (@richfitz, #100)
pkgbuild_process() and build() now use colored compiler diagnostics if supported (#102)
Avoid documentation link ambiguity in R 4.1 (#105)

compile_dll() now supports automatic cpp11 registration if the package links to cpp11.
rtools_needed returns correct version instead of “custom” (@burgerga, #97)

Support for RTools 40 and custom msys2 toolchains that are explicitly set using the CC Makevars (#40).

check_build_tools() gains a quiet argument, to control when the message is displayed. The message is no longer displayed when check_build_tools() is called internally by pkgbuild functions. (#83)

build() gains a clean_doc argument, to control if the inst/doc directory is cleaned before building. (#79, #75)
build() and pkgbuild_process now have standard output and error are correctly interleaved, by redirecting the standard error of build process to the standard output (@gaborcsardi, #78).
check_build_tools() now has a more helpful error message which points you towards ways to debug the issue (#68).
pkgbuild_process now do not set custom compiler flags, and it uses the user’s Makevars file (@gaborcsardi, #76).
rtools_path() now returns NA on non-windows systems and also works when has_rtools() has not been run previously (#74).

build() and compile_dll() gain a register_routines argument, to automatically register C routines with tools::package_native_routines_registration_skeleton() (#50)
build() will now warn if trying to build packages on R versions <= 3.4.2 on Windows with a space in the R installation directory (#49)
build() will now message if a build contains long paths, which are unsupported on windows (#48)
compile_dll() no longer doubles output, a regression caused by the styling callback. (https://github.com/r-lib/devtools/issues/1877)
build() output is now styled like that in the rcmdcheck package (https://github.com/r-lib/devtools/issues/1874).
build() no longer sets compile flags (#46)

Preliminary support for rtools 4.0 (#40)
compile_dll() now does not supply compiler flags if there is an existing user defined Makevars file.
local_build_tools() function added to provide a deferred equivalent to with_build_tools(). So you can add rtools to the PATH until the end of a function body.

Add metadata to support Rtools 3.5 (#38).
build() only uses the --no-resave-data argument in R CMD build if the --resave-data argument wasn’t supplied by the user (@theGreatWhiteShark, #26)
build() now cleans existing vignette files in inst/doc if they exist. (#10)
clean_dll() also deletes symbols.rds which is created when compile_dll() is run inside of R CMD check.
First argument of all functions is now path rather than pkg.
