Hi I'm trying to build just one cxx file specifically rtkprojectgeometricphantom.cxx
I copied rtkprojectgeometricphantom.cxx, rtkprojectgeometricphantom.cxx, CMakeLists.txt to new directory. and in CMakeLists.txt, I added three lines cmake_minimum_required(VERSION 3.9.5 FATAL_ERROR) > find_package(Gengetopt REQUIRED) > project(rtkprojectgeometricphantom) here is an error message. CMake Error at CMakeLists.txt:3 (find_package): By not providing "FindGengetopt.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "Gengetopt", but CMake did not find one. Could not find a package configuration file provided by "Gengetopt" with any of the following names: GengetoptConfig.cmake gengetopt-config.cmake Add the installation prefix of "Gengetopt" to CMAKE_PREFIX_PATH or set "Gengetopt_DIR" to a directory containing one of the above files. If "Gengetopt" provides a separate development package or SDK, be sure it has been installed. Configuring incomplete, errors occurred! I need to set an Gengetopt_DIR. at first I set the directory where rtkprojectgeometricphantom.ggo is but It didn't work and than I set the directory where FindGengetopt.cmake is It still didn't work. I think I need to find the directory of GengetoptConfig.cmake or gengetopt-config.cmake how can I build only one cxx file?
