CMakePCHCompiler
A CMake module providing precompiled header support via custom CXXPCH/CPCH compiler extensions, now obsolete since CMake 3.16.
What is CMakePCHCompiler?
CMakePCHCompiler is a CMake module that adds precompiled header (PCH) support to CMake projects by defining custom CXXPCH and CPCH meta-compilers. It compiles header files into precompiled headers, speeding up build times by reusing parsed headers across source files. The project is now obsolete as native PCH support was added in CMake 3.16.
C/C++ developers using CMake 3.0–3.15 who need precompiled header support to accelerate compilation times in large projects.
It provides a simpler, more transparent alternative to other PCH modules by ensuring compiler flag consistency and requiring no source code changes, though it's no longer maintained due to native CMake support.
