CMake error with MRPT

[arnaudgelas]

CMake Error at CMakeLists.txt:12 (FIND_PACKAGE):
Could not find module FindMRPT.cmake or a configuration file for package
MRPT.

Adjust CMAKE_MODULE_PATH to find FindMRPT.cmake or set MRPT_DIR to the
directory containing a CMake configuration file for MRPT. The file will
have one of the following names:

 MRPTConfig.cmake
 mrpt-config.cmake

I found this issue while googling for the same error while I was building MRPT navigation/localization from source. It turned out that I was missing the libmrpt-dev package that provided those files. On Ubuntu, that was fixed by running the following:
sudo apt-get install libmrpt-dev
