MidasConfig.cmake usage |
|
|
As the Midas software is installed using CMake, it can be easily integrated into
other CMake projects using the MidasConfig.cmake file produced during the Midas
installation.
This file points to the location of the include and libraries of Midas using three
variables:
- MIDAS_INCLUDE_DIRS
- MIDAS_LIBRARY_DIRS
- MIDAS_LIBRARIES
Then the CMakeLists file of the new project can use the CMake find_package
functionalities like:
```
find_package (Midas REQUIRED)
if (MIDAS_FOUND)
MESSAGE(STATUS "Found midas: libraries ${MIDAS_LIBRARIES}")
pbuilder_add_ext_libraries (${MIDAS_LIBRARIES})
else (MIDAS_FOUND)
message(FATAL "Unable to find midas")
endif (MIDAS_FOUND)
include_directories (${MIDAS_INCLUDE_DIR})
```
pbuilder_add_ext_libraries is a CMake macro allowing to automatically add the
libraries into the project: this macro can be found here:
https://github.com/project8/scarab/blob/master/cmake/PackageBuilder.cmake
If such macro doesn't exist, the linkage to each executable/library can be done
similarly to https://midas.triumf.ca/elog/Midas/1964 using:
```
target_link_libraries(crfe ${MIDAS_LIBARIES} ${LIBS})
```
The current version of the MidasConfig.cmake is minimal and could for example
include a version number: this would allow to define a e.g. minimal version of
Midas needed by the new project. |
