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.

Build and exectution instructions

Build the lib

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

Build the client app

From the root of the project:

cd client
mkdir build && cd $_
cmake .. -Dpont_ROOT=../../lib/install && make

Running the client

In the client's build folder:

./client
