This project shows how to make CMake config files for client applications using a modern CMake approach.
The goal is to make things as simple as possible for the client. Users
shouldn't have to do anything more than add the appropriate
target_link_libraries(...) command to their CMakeLists.txt to have all the
required compiler flags, includes and libraries added automatically by CMake.
Furthermore this example shows how to make a relocatable CMake package (the installation folder can be moved and other than building the client with the updated library install path, no changes are necessary).
The library should be usable both when installed or directly included in
another CMake project. To achieve this, an ALIAS such as pont::pont must be
added in the library's CMakeLists.txt file. Client apps should only use the
namespace qualified target regardless of if they use it installed or embedded.
cd lib
mkdir build && cd $_
# You can choose to activate OpenMP or not. To test the transitive
# dependencies, it needs to be activated
cmake .. -DCMAKE_INSTALL_PREFIX=../install -DWITH_OPENMP=TRUE && make install
From the root of the project:
cd client
mkdir build && cd $_
cmake .. -Dpont_ROOT=../../lib/install && make
In the client's build folder:
./client
