CMake express the "greater or equal" statement

I know that in CMake I can check for the compiler version like this

if(MSVC_VERSION LESS 1700)
... // MSVC is lower than MSVC2012

but how do I express this in CMake syntax?

if(MSVC_VERSION GREATER_OR_EQUAL_TO 1700)
... // MSVC greater or equal to MSVC2012
Solution

  • Update for CMake 3.7 and later:

    CMake 3.7 introduced a couple of new comparisons for if, among them GREATER_EQUAL:

    if(MSVC_VERSION GREATER_EQUAL 1700)
    [...]

    Original answer for older CMake versions:

    if((MSVC_VERSION GREATER 1700) OR (MSVC_VERSION EQUAL 1700))
  [...]

    Or probably better, as it avoids repeating the condition:

    if(NOT (MSVC_VERSION LESS 1700))
  [...]
