Add test case to verify CMake does not re-run on first build Extend the RunCMake.Configure with a case to verify that the CMake configuration process does not immediately re-run the first time that the generated build system is invoked. 2014-01-21 11:33:56 -05:00			`set(input ${CMAKE_CURRENT_BINARY_DIR}/CustomCMakeInput.txt)`

Allow projects to specify extra inputs to CMake Define a new 'CMAKE_CONFIGURE_DEPENDS' directory property that projects can use to specify input files to the CMake configuration process. Extend the RunCMake.Configure test to verify that the build system re-runs CMake when this input changes. 2014-01-21 14:14:49 -05:00
