[QE-users] Why does normal QE build require to compile GPU dependent routines ?

[Husak Michal]

Hi

I am tiring to recompile QE  7.1 under Windows + cygwin64 (environment described in another E-mail).
I am able to get a pure serial QE version (no MP no MPI) in such way passing the QE test-suite ...
if I try MP or MPI build, I get error message below ...
I do not understand why a standard QE is built with GPU depended routines when I do not request any GPU
support ....
I used
./configure   --enable-openmp   --disable-parallel
and
./configure   --disable-openmp   --enable-parallel

Any glue what can be wrong ?

QE 6.7 building does not show this issue ...
