mk_pch — Build pre-compiled header
MODULES="... compiler ..."
mk_pch SOURCE=source options...
SOURCE=sourceIndicates the header file to compile.
...
Common options are documented in the compiler module.
Defines a target to build a pre-compiled C/C++ header file. Sets
result to the generated target. By default, the correct
language to use is guessed based on the file extension. Use
the COMPILER option to choose explicitly (e.g. compile
a .h file with the C++ compiler).
It is generally preferable to avoid explicitly building pre-compiled
headers and instead pass the header to compile directly to the
PCH option to mk_program et al.
This helps ensure that the header is compiled with the same set of
compiler flags and for the correct language.
