           Summary: Projects and subdirectories guarded by IF() depending
                    on CMake options are not changed when option changes
           Product: kdevelop
           Version: 4.2.0
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: Build tools: CMake
        AssignedTo: kdevelop-bugs@kdevelop.org
        ReportedBy: kde@opensource.sf-tec.de


Version:           4.2.0 (using KDE 4.6.1) 
OS:                Linux

Use this CMakeLists.txt:

PROJECT(TestOption)

OPTION(WITH_OPTIONAL "build the optional target" OFF)

IF (WITH_OPTIONAL)
    FILE(WRITE ${CMAKE_CURRENT_BINARY_DIR}/opt.c "int main(void) { return 0;
}")
    ADD_EXECUTABLE(optional_target ${CMAKE_CURRENT_BINARY_DIR}/opt.c)
ENDIF()

FILE(WRITE ${CMAKE_CURRENT_BINARY_DIR}/def.c "int main(void) { return 0; }")
ADD_EXECUTABLE(default_target ${CMAKE_CURRENT_BINARY_DIR}/def.c)

When the project is imported only one project is shown. Now go to the project
configuration and enable the option. When you build you see that the option is
set and the second project is build, too. But KDevelop still shows only one
project.

The same happens when you set the default of the option to true: the two
projects are always shown, even if the option is deactivated.

Reproducible: Always
