Compilation KO on debian

[fghoussen]

As it seems there is no debian package for Pangolin, I build it from source:

/tmp> cat /etc/os-release 
PRETTY_NAME="Debian GNU/Linux trixie/sid"
/tmp> g++ --version
g++ (Debian 13.2.0-9) 13.2.0

/tmp/Pangolin/build> cmake -DCMAKE_INSTALL_PREFIX=/tmp/Pangolin/local
/tmp/Pangolin/build> make all install

/tmp/Pangolin> cat local/lib/cmake/Pangolin/PangolinConfig.cmake 
# Compute paths
get_filename_component( PROJECT_CMAKE_DIR "${CMAKE_CURRENT_LIST_FILE}" PATH )
# Library dependencies (contains definitions for IMPORTED targets)
if( NOT Pangolin_BINARY_DIR )
  include( "${PROJECT_CMAKE_DIR}/PangolinTargets.cmake" )
endif()
SET( Pangolin_CMAKEMODULES /tmp/Pangolin/cmake )
SET( Pangolin_LIBRARIES    pango_core;pango_display;pango_geometry;pango_glgeometry;pango_image;pango_opengl;pango_packetstream;pango_plot;pango_python;pango_scene;pango_tools;pango_vars;pango_video;pango_windowing;tinyobj )
SET( Pangolin_LIBRARY      "${Pangolin_LIBRARIES}" )
include(CMakeFindDependencyMacro)
find_dependency(Eigen3)
if (UNIX)
  find_dependency(Threads)
endif()

/tmp/Pangolin> git log -1
commit 099f298d785b757c8691b88a90210d99c5fcf143 (HEAD -> master, origin/master, origin/HEAD)

Now Trying to build this repo doesn't work:

/tmp/SensorsCalibration/lidar2lidar/manual_calib/build> git log -1
commit 1b701c11eed6c96e23fe13b98430a510a91d3498 (HEAD -> master, origin/master, origin/HEAD)

How to fix this compilation error?

I have just tried to force include paths but compilation fails:

did you solve this?

Found solution in issue #102 Change CMAKE to:
