No one has anything to say about this?
CMake seems to do more than just add them as general compiler flags,
it seems to know exactly which attributes in the VCPROJ XML are
mapped to their respective command line alternatives, and uses the
appropriate ones. If this is true, why do we not have a dedicated
target & source file property that I can use to enable precompiled
headers instead of using these command line strings directly? Am I
misunderstanding something?
Nothing magic going on. With VS 2010 and greater, there is a python
script that creates a flag mapping table from MS xml:
http://cmake.org/gitweb?p=cmake.git;a=blob;f=Source/cmparseMSBuildXML.py;h=4877e5913436dcf117580db286566b4f9568fc20;hb=HEAD
cmparseMSBuildXML.py
So, nothing specific was done for pre-compiled headers. To have them
work cross platform is very difficult because of the wide variety in API
by the compilers out there.
