[Cmake] Bug in 2.0.2: How to do configuration specific options inthe MS Visual Studio Projects

[Rajiv Bhagwat]

1. During 'configure', I get the error:
Parse error. Function missing ending ")". Instead found "("
indicating the line containing $(IntDir).

2. I had read about 'debug - optimised' modifiers. When tried, found the
following problems with it:

2a. How to get the lib for each of the 4 builds (Debug, Release, MinSizeRel
& RelWithDebInfo) is not very clear.. Two options-> Four combinations seems
ok, till you get: debug+optimised = RelWithDebInfo???
Use of a single modifier such as either of: D,R,M,I or 0-3 would be clearer.

2b. Testing with only 1 library, I used:
TARGET_LINK_LIBRARIES(progname libname debug )
Which crashed CMake with a big thud... Should I try 'progname debug
libname'? I assumed 'debug' would apply to the previous libname, the
document says otherwise.

2c. How exactly should the library path be specified if using the 'debug ..'
modifiers? i.e. Would CMake not have to figure out the directory and insert
it in path just before '/libname.lib'?
i.e. use of
TARGET_LINK_LIBRARIES(progname ${PRJ_PATH}/winbuild/libname.lib)
instead of:
TARGET_LINK_LIBRARIES(progname ${PRJ_PATH}/winbuild/$(IntDir)/libname.lib)
appears confusing, when we know that there is an option dependant directory
in-between.

Have been playing with CMake for 6 months or so, but space+time
considerations of compiling every library as a part of every project was not
very attractive...
