Still running into "blasfeo_targets.h" not found issue on Ubuntu 20.04

[NathanWeasley]

Hi developers:

I cloned ct v3.0.2 to my ubuntu 20.04 and used control-toolbox/ct/install_hpipm.sh to install hpipm and blasfeo, however when building optimal control projects I got error:

/home/nathan/Documents/ros_wrkspace/tiltplan_wrk/devel/include/ct/optcon/solver/lqp/HPIPMInterface.hpp:12:10: fatal error: blasfeo_target.h: No such file or directory
12 | #include <blasfeo_target.h>

The cpp files that included this file are from ct_models.

I checked this link and tried both formation (with and without _LIBRARIES suffix) and neither worked for me.

I tried to print the ${blasfeo_INCLUDE_DIRS} and ${hpipm_INCLUDE_DIRS} and they are both empty.

Please help me once you got time. Thanks!
