[Cmake] Environment variables

[Nils H. Busch]

Hello,

is it possible with CMake to query unix environment variables and set
CMake vars accordingly,
something like SET(A_CMAKE_VAR "$(A_UNIX_VAR)") ?

Is it possible to read/convert information from a project not generated
by CMake e.g. makefile content into a CMake project ? Basically, I want
to convert variables in Makefile convention ($(A_VAR)) to CMake
variables.

Thanks.
