error during the configuration with cmake

[weslleyspereira]

It may be caused by an older CMake. The operator VERSION_GREATER_EQUAL was introduced in CMake 3.7 (https://cmake.org/cmake/help/latest/command/if.html#version-greater-equal), and ScaLAPACK only asks for CMake 3.2:

scalapack/CMakeLists.txt

Line 1 in 5bad748

cmake_minimum_required(VERSION 3.2)

One possible solution is to ask for CMake 3.7 in ScaLAPACK:

diff --git a/CMakeLists.txt b/CMakeLists.txt
index 0c33719..0216bfa 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt
@@ -1,4 +1,4 @@
-cmake_minimum_required(VERSION 3.2)
+cmake_minimum_required(VERSION 3.7)
 
 project(SCALAPACK VERSION 2.2.1 LANGUAGES C Fortran)

[Update:] I implemented this solution at #65.

Hi @GengSS. Could you verify if #65 solves this issue. Thanks!

Dear @weslleyspereira , thank you very much.
I tested the solution and switched to a recent version for CMake, and it solved the issue.
