[Ipopt] Variable 'MKLROOT' not defined in ipopt.pc

[Eric Antonelo]

Dear all,

I've tried to make install ipopt, but I get the following error:

Variable 'MKLROOT' not defined in
'/home/eric/Software/CoinIpopt/build/lib/pkgconfig/ipopt.pc'

But MKLROOT is set in bash correctly to
/home/eric/intel/compilers_and_libraries_2019.5.281/linux/mkl

Do you have any idea of what could be causing this?

Below, more details of the output of make install:



test -z "/home/eric/Software/CoinIpopt/build/share/coin/doc/Ipopt" ||
mkdir -p -- "/home/eric/Software/CoinIpopt/build/share/coin/doc/Ipopt"

for file in README AUTHORS LICENSE ; do \

  if test -f "$file"; then dir=; else dir="../../Ipopt/"; fi; \

  if test -f "$dir$file"; then /usr/bin/install -c -m 644 "$dir$file"
"/home/eric/Software/CoinIpopt/build/share/coin/doc/Ipopt/$file"; fi;
\

done
