CMake cannot find the CVB package

Programming Questions C++ API

I have installed CVB, buildessentials and cmake, but cmake cannot find cvb. The following error message appears when running cmake.
My system Ubuntu 20.04 x64. The CVB named “cvb-13.04.003-ubu2004-x86_64” was installed. The system was rebooted after the installation.
My CMakeLists.txt:

cmake_minimum_required(VERSION 3.5)

project(Vector_GEV)

set (CMAKE_CXX_STANDARD 14)

if(UNIX AND CMAKE_CXX_COMPILER_VERSION VERSION_LESS 9 AND CMAKE_C_COMPILER_VERSION VERSION_LESS 9)
	#find boost
	FIND_PACKAGE( Boost 1.67 COMPONENTS filesystem REQUIRED )
	INCLUDE_DIRECTORIES( ${Boost_INCLUDE_DIR} )
endif()

#find CVB
file(TO_CMAKE_PATH "$ENV{CVB}/cmake" CVB_MODULE_PATH)
set(CMAKE_MODULE_PATH "${CMAKE_MODULE_PATH}" "${CVB_MODULE_PATH}")
find_package(CVB REQUIRED)

add_executable(${PROJECT_NAME} main.cpp )

target_link_libraries(${PROJECT_NAME} CVB::CvbGevServer)

target_compile_features(${PROJECT_NAME} PUBLIC cxx_std_17)

if(UNIX)
  target_link_libraries(${PROJECT_NAME} ${Boost_LIBRARIES} -lpthread)
  target_link_libraries(${PROJECT_NAME} pthread)
endif()

The Error:

CMake Error at CMakeLists.txt:16 (find_package):
  By not providing "FindCVB.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "CVB", but
  CMake did not find one.

  Could not find a package configuration file provided by "CVB" with any of
  the following names:

    CVBConfig.cmake
    cvb-config.cmake

  Add the installation prefix of "CVB" to CMAKE_PREFIX_PATH or set "CVB_DIR"
  to a directory containing one of the above files.  If "CVB" provides a
  separate development package or SDK, be sure it has been installed.


-- Configuring incomplete, errors occurred!

I have come across this error a few times in the past. I think that at that time a reinstallation of cvb helped.
But when I look in “/opt/” I find there also cvb with all components, nothing seems to be missing.

Okay, something seems to have gone wrong. I had run “sudo apt --fix-broken install” and /opt/cvb… was removed.
After reinstalling cvb, the error appears:

Failed to retrieve/decode the log configuration for module GEVSVC: Failed to connect to the shared memory with connection info: No such file or directory
