I have a CMakeLists.txt file that builds a bunch of prerequisite
library, and then my application I'm working on.
This is done all with External_Project macros. Once everything I need
is built, I build my code as an external project:
set(proj BRAINSTracerQT)
ExternalProject_Add(${proj}
URL file://${CMAKE_CURRENT_SOURCE_DIR}/${proj}
SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/${proj}
DOWNLOAD_COMMAND ""
DEPENDS ${VTK_DEPEND} ${SEM_DEPEND}
CMAKE_GENERATOR ${gen}
CMAKE_ARGS
${LOCAL_CMAKE_BUILD_OPTIONS}
-DModuleDescriptionParser_DIR:PATH=${MDP_DIR}
-DITK_DIR:PATH=${ITK_DIR}
-DVTK_DIR:PATH=${VTK_DIR}
-DQT_QMAKE_EXECUTABLE:FILEPATH=${QT_QMAKE_EXECUTABLE}
INSTALL_DIR ${BRAINSTracer_BINARY_DIR}
UPDATE_COMMAND ""
)
Everything worked in CMake 2.8.1, now I get the errors below. Very weird.
