There is already an established mechanism to do this.  It is based on 
the FIND_PACKAGE command along with the "PackageConfig.cmake" mechanism. 
  See "Mastering CMake" section 6.7 for a detailed description.  There 
are also examples in the open-source projects at www.vtk.org, 
www.itk.org, www.paraview.org, and vxl.sourceforge.net.
