This is a simple CMake project for demonstrating and testing the implementation the xSDK specification for compatible CMake projects.
To configure and run the tests, just do:
$ mkdir BUILD $ cd BUILD $ cmake \ -D C_COMPILER_1=<fullPathC1> \ -D C_COMPILER_2=<fullPathC2> .. -D CXX_COMPILER_1=<fullPathCxx1> \ -D CXX_COMPILER_2=<fullPathCxx2> .. -D Fortran_COMPILER_1=<fullPathFortran1> \ -D Fortran_COMPILER_2=<fullPathFortran2> .. $ ctest -j12
Here, a default C, C++, and Fortran compiler should also be found (by CMake
searching ${PATH}) which should be different than these two compilers
<fullPathCxx1> and <fullPathCxx2>. These all have defaults set up to
look for standard GCC compilers installed in /usr/bin/. But the default
compilers found by CMake should be in another directory. See the file
CMakeLists.txt for details.
The XSDK defaults and behaviors are implemented in the reusable stand-alone
CMake module xsdk/XSDKDefaults.cmake. This directory can be snapshotted
into other projects that want to use this CMake module (see
[snapshot-dir.py](https://tribits.org/doc/TribitsDevelopersGuide.html#snapshot-dir-py-help)).
This particular GitHub CMake project XSDKCmakeProj tests the behavior of the
module XSDKDefaults.cmake by using a mock XSDK CMake project which is
contained in the directory:
example_driver/
which contains a single CMakeLists.txt file. See that file for where to
include the XSDKDefaults.cmake module.
For more details about XSDKDefaults.cmake, see the documentation at the top the file XSDKDefaults.cmake.
NOTE: The outer test CMake project snapshots TriBITS core in order to use the
TRIBITS_ADD_ADVANCED_TEST() function in order to make it easier to write
stronger tests for XSDKDefaults.cmake. But this is not a TriBITS
project.
