[CMake] ADD_CUSTOM_TARGET

[Brad Bell]

I am trying to build a project for Red-hat 6 which uses the following cmake version

    bradbell@gorst trash]$ cmake --version
    cmake version 2.6-patch 4



Below is an example CMakeLists for which
    make check
works with cmake 2.8.9 and fails with 2.6-patch 4:
    CMAKE_MINIMUM_REQUIRED(VERSION 2.6)
    #
    PROJECT(hello)
    #
    ADD_EXECUTABLE(hello_one EXCLUDE_FROM_ALL hello_one.cpp )
    ADD_EXECUTABLE(hello_two EXCLUDE_FROM_ALL hello_two.cpp )
    #
    ADD_CUSTOM_TARGET(check_one hello_one DEPENDS hello_one)
    ADD_CUSTOM_TARGET(check_two hello_two DEPENDS hello_two)
    #
    ADD_CUSTOM_TARGET(check DEPENDS check_one check_two)



[bradbell@gorst trash]$ ./cmake_target.sh

[bradbell@gorst trash]$

While doing so I am having trouble with the ADD_CUSTOM_TARGET. To be specifc, after building a custom target, cmake seems to forget it has done so. I am attaching a bash script that creates the necessary files and runs the make check command. The output I get on Red-Hat 6 is make[3]: *** No rule to make target `check_one', needed by `CMakeFiles/check'. Stop.
