CMake Error at cmake/macros/macro_configure_feature.cmake:112 (MESSAGE):

Could not find the scalapack library!

Could not find a sufficient SCALAPACK installation:

SCALAPACK symbol check for pdsyevr_ and pssyevr_ failed! This usually means
that your SCALAPACK installation is incomplete or the link line is broken.
Consult

CMakeFiles/CMakeError.log

for further information.

Please ensure that a suitable scalapack library is installed on your
computer.

If the library is not at a default location, either provide some hints for
autodetection, or set the relevant variables by hand in ccmake.

I would suggest to provide hints for directories and let cmake try to find them.

dealii/cmake/modules/FindDEAL_II_SCALAPACK.cmake

Lines 25 to 26 in b9ad0d3

	set(SCALAPACK_DIR "" CACHE PATH "An optional hint to a SCALAPACK directory")
	set(BLACS_DIR "" CACHE PATH "An optional hint to a BLACS directory")

Specifying libraries directly is cumbersome and error prone. Does the following option for scalapack work for you?

-D SCALAPACK_DIR=${MKLROOT}
