CMake Error at /usr/local/share/cmake-3.15/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find SWIG (missing: SWIG_DIR) (Required is at least version "4")
Call Stack (most recent call first):
  /usr/local/share/cmake-3.15/Modules/FindPackageHandleStandardArgs.cmake:378 (_FPHSA_FAILURE_MESSAGE)
  /usr/local/share/cmake-3.15/Modules/FindSWIG.cmake:64 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  swig/CMakeLists.txt:20 (find_package)

FindSwig.cmake uses the following command

if(SWIG_EXECUTABLE)
  execute_process(COMMAND ${SWIG_EXECUTABLE} -swiglib
    OUTPUT_VARIABLE SWIG_swiglib_output
    ERROR_VARIABLE SWIG_swiglib_error
    RESULT_VARIABLE SWIG_swiglib_result)

which later fills SWIG_DIR.

However the given path is wrong (conan instead of rea) resulting with the above error.

${SWIG_EXECUTABLE} =  /home/rea/.conan/data/swig_installer/4.0.1/bincrafters/stable/package/44fcf6b9a7fb86b2586303e3db40189d3b511830/bin/swig

${SWIG_swiglib_output} = /home/conan/.conan/data/swig_installer/4.0.1/bincrafters/stable/package/44fcf6b9a7fb86b2586303e3db40189d3b511830/share/swig/4.0.1

@rea-yseop
This recipe will soon be available on CCI (conan-io/conan-center-index#1717)

Look at its test_package, I have added a working cmake example.
It is currently not used in the conanfile because cci has currently no python recipe yet.

This works. Thank you :)
