Could not find a package configuration file provided by "trajopt"

[mohamedsayed18]

I tried to build the trajopt first using catkin build trajoptand it built successfully
then I tried to build the whole workspace using catkin build I got the following error

Errors     << pick_and_place:cmake /media/mohamed/C03CCDB43CCDA62E/work/Mx3D/optimized_planning_ws/logs/pick_and_place/build.cmake.003.log

I checked if the file exist using find . -iname "trajopt-config*"

./build/trajopt/trajopt-config-version.cmake

I solved the problem by setting the trajopt_DIR in the pick_and_place/CMakeLists.txt as follows

set(trajopt_DIR /media/mohamed/C03CCDB43CCDA62E/work/optimized_planning_ws/src/trajopt_ros/trajopt)
find_package(trajopt REQUIRED)
