CMake and NSIS has never been ported to work on Linux, so no surprise there.

The project command by default asks for c/c++ compiler.

You want:
project(NONE)


  cmake --help-command project

      Set a name for the entire project.

          project(<projectname> [languageName1 languageName2 ... ] )

     Sets the name of the project.  Additionally this sets the variables
        <projectName>_BINARY_DIR and <projectName>_SOURCE_DIR to the
        respective values.

   Optionally you can specify which languages your project supports.
   Example languages are CXX (i.e.  C++), C, Fortran, etc.  By default C
   and CXX are enabled.  E.g.  if you do not have a C++ compiler, you can
   disable the check for it by explicitly listing the languages you want
   to support, e.g.  C.  By using the special language "NONE" all checks
   for any language can be disabled.
