<h2> Using the cmake installed AMDiS in your project </h2> <h2> Using the cmake installed AMDiS in your project </h2>
A cmake-project consists of the source files and a file CMakeLists.txt, which contains a description of needed libraries, headers and programs. If you have a simple project with one program "fooProg", which have to compile only one source file "src/foo.cc", your CMakeLists.txt consist of the following lines:
<p class="desc" >
project(projectName) <br>
cmake_minimum_required(VERSION 2.8)<br><br>
find_package(AMDiS REQUIRED)<br>
if(AMDiS_FOUND)<br>
include(${AMDiS_USE_FILE})<br>
add_executable(fooProg src/foo.cc)<br>
target_link_libraries(fooProg ${AMDiS_LIBRARIES})<br>
endif(AMDiS_FOUND)<br>
</p >
The first two lines
<p class="desc" >
project(projectName) <br>
cmake_minimum_required(VERSION 2.8)
</p >
tell cmake the name of your project and that you whish to use only cmake versions newer than 2.8.<br>
The line
<p class="desc" >
find_package(AMDiS REQUIRED)
</p >
tells cmake, that you want to use AMDiS and it should complain if AMDiS was not found. CMake will print an error message, bu will not stop the execution! With the command
<p class="desc" >
include(${AMDiS_USE_FILE})
</p >
we read an AMDiS specific configuration file, which sets some compilerflags and adds the include directorys. The program is added with
<p class="desc" >
add_executable(fooProg src/foo.cc)
</p >
and we have to tell cmake, that we need the library amdis and each library amdis depends on. This is done with the command
<p class="desc" >
target_link_libraries(fooProg ${AMDiS_LIBRARIES})
</p >
If cmake does not find AMDiS, you have to set the variable AMDiS_DIR to the directory containing the file AMDiSConfig.cmake. This file resides in
<p class="desc" >
$CMAKE_INSTALL_PREFIX/share/amdis/
</p >
