CMake missing environment variables errors
The 2nd and later optional args to the PROJECT command should be known CMake language values.
It's typical values are:
- leave it off, don't provide a 2nd arg (default to C and CXX)
- C
- CXX
- Fortran
- NONE
You've provided "On" as a language value to the PROJECT command, which CMake does not know.
Remove the "On" and leave it blank or replace it with the languages you need for your project.

I'm attempting to use cmake on Mac OSX i've installed both a binary version and then also from source. However i continue to receive the following errors when attempting to create a Makefile.
cpc1-dumb4-2-0-cust166:build bcrowhurst$ cmake . CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_On_COMPILER_ENV_VAR
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_On_COMPILER
CMake Error: Could not find cmake module file:/Users/bcrowhurst/NetBeansProjects/appon/build/CMakeFiles/CMakeOnCompiler.cmake CMake Error: Could not find cmake module file:CMakeOnInformation.cmake CMake Error: CMAKE_On_COMPILER not set, after EnableLanguage -- Boost version: 1.43.0 -- Found the following Boost libraries: -- system -- Configuring incomplete, errors occurred!
My CMakeLists.txt is as follows:
cmake_minimum_required( VERSION 2.6 ) project( Application On ) find_package( Boost COMPONENTS system REQUIRED ) link_directories( ${Boost_LIBRARY_DIRS} ) if(Boost_FOUND) include_directories( ${Boost_INCLUDE_DIRS} ) add_library( object ../source/object.cpp ../source/object.h ) target_link_libraries( object ${Boost_SYSTEM_LIBRARY} ) endif()
Any help would be greatly appreciated.
Thanks.
