Error while including CURLCPP with CMake #113

Closed stav121 closed 7 years ago

Good evening,

I've included CURLCPP in my project but I'm facing a weird problem while I include it with CMake in my project:

ADD_SUBDIRECTORY(source_code/external_includes/curlcpp) INCLUDE_DIRECTORIES(${CURLCPP_SOURCE_DIR}/include)

I have no problem compiling normally from the command line , it's just my CMake that has the problem.

It's not a major issue, but I leave it here in case someone can find a solution!

Thanks in advance :)

Closed : Found the answer, I had a bad line in my CMakeLists.txt , changed it and everything got fixed.
