cmake-precompiled-header

Precompiled header setup for CMake. Supported CMake generators:

• Visual Studio
• NMake Makefiles
• Unix Makefiles (GCC)
• MinGW Makefiles
• MSYS Makefiles
• Ninja

Usage

Create a pchheader.{c,cpp} and pchheader.h and add then to the CMake target:

add_library(target ... pchheader.cpp pchheeader.h)

pchheader.h can include all the huge header files that are used everywhere in your project:

#include <string>
#include <iostream>
#include <list>
#include <map>

pchheader.{c,cpp} should just include the header file:

#include "pchheader.h"

In your main CMakeLists.txt, include the macro file:

include(PrecompiledHeader.cmake)

Then add this line, to set up precompiled headers:

add_precompiled_header(target pchheader.h FORCEINCLUDE)

Additional documentation is in PrecompiledHeader.cmake.
