Gravity will look for the h files too: https://github.com/coin-or/Gravity/blob/master/cmake/FindIPOPT.cmake#L46
you can add more HINTS to this cmake file or just specify the root directory to Ipopt using export IPOPT_ROOT_DIR="path"

No, IPOPT_ROOT_DIR doesn't work.

You should use:

pkg_check_modules(IPOPT REQUIRED IMPORTED_TARGET ipopt)

from gravity.

It has worked so far, I do realize you can use pkg_config, but I wouldn't consider this an "issue".

No, it doesn't work with -DIPOPT_ROOT_DIR=/usr/local:

-- Enable IPOPT
Looking for Ipopt in /usr/local
Cannot find Ipopt, will try pulling it from github.
-- Configuring done
-- Generating done

from gravity.

I printed variables:

message(STATUS "IPOPT_INCLUDE_DIR=${IPOPT_INCLUDE_DIR}")
message(STATUS "IPOPT_LIBRARY=${IPOPT_LIBRARY}")
message(STATUS "IPOPT_LIBRARY2=${IPOPT_LIBRARY2}")
find_package_handle_standard_args(IPOPT DEFAULT_MSG IPOPT_LIBRARY IPOPT_LIBRARY2 IPOPT_INCLUDE_DIR)

It printed:

Looking for Ipopt in /disk-samsung/freebsd-ports/math/gravity/work/.build/third_party/Install/ipopt/build
-- IPOPT_INCLUDE_DIR=/usr/local/include/coin
-- IPOPT_LIBRARY=/usr/local/lib/libipopt.so
-- IPOPT_LIBRARY2=
Cannot find Ipopt, will try pulling it from github.
-- Configuring done
-- Generating done
-- Build files have been written to: /disk-samsung/freebsd-ports/math/gravity/work/.build

Both IPOPT_INCLUDE_DIR and IPOPT_LIBRARY are found, but it still says that it can't find ipopt.
