ENH: move the code which queries gcc for the system include dirs from
CMakeSystemSpecificInformation.cmake into a separate file, CMakeEclipseCDT4.cmake -if CMAKE_EXTRA_GENERATOR is set, i.e. either CodeBlocks or KDevelop3 or EclipseCDT4, load a matching cmake script file, which can do things specific for this generator - added such files for Eclipse, KDevelop and CodeBlocks, one thing they all do is they try to find the respective IDE and store it in the CMAKE_(KDEVELOP3|CODEBLOCKS|ECLIPSE)_EXECUTABLE variable. This could be used by cmake-gui to open the project it just generated with the gui (not sure this is possible with eclipse). Alex
