A common repository for CMake Modules which are not distributed with CMake but are commonly used by ROS packages.

This makes it alot easier to include external package in catkins build system in ROS.

See the CONTRIBUTING.md file in this repository before submitting pull requests for new modules.

1. Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.
2. NumPy is the fundamental package for scientific computing with Python.
3. TBB lets you easily write parallel C++ programs that take full advantage of multicore performance.
4. TinyXML is a simple, small, C++ XML parser.
5. Xenomai is a real-time development framework cooperating with the Linux kernel.

To use the CMake modules provided by this catkin package, you must <build_depend> on it in your package.xml, like so:

<?xml version="1.0"?>
<package>
  <!-- ... -->
  <build_depend>cmake_modules</build_depend>
</package>

Then you must find_package it in your CMakeLists.txt along with your other catkin build dependencies:

find_package(catkin REQUIRED COMPONENTS ... cmake_modules ...)

OR by find_package'ing it directly:

find_package(cmake_modules REQUIRED)

After the above find_package invocations, the modules provided by cmake_modules will be available in your CMAKE_MODULE_PATH to be found. For example you can find Eigen by using the following:

find_package(Eigen REQUIRED)

find_package(Eigen REQUIRED)

find_package(NUMPY REQUIRED)

find_package(TBB REQUIRED)

find_package(TinyXML REQUIRED)

find_package(Xenomai REQUIRED)
