STB not found

[GPSnoopy]

The CMake files assume you've called one of the vcpkg_* script before. It's designed to use its own dependencies rather than any system-wide package/files.

[meerfrau]

And what if I would like to package it for my distribution (and thus use the system libs)?

[GPSnoopy]

Then it gets a bit iffy. Exact CMake code will be dependent on the versions of CMake and the libraries you have; also not all libraries might be supported/have an existing find_package script.

The relevant code is here:

RayTracingInVulkan/CMakeLists.txt

Lines 50 to 57 in 9e4b225

	find_package(Boost REQUIRED COMPONENTS exception program_options)
	find_package(freetype CONFIG REQUIRED)
	find_package(glfw3 REQUIRED)
	find_package(glm CONFIG REQUIRED)
	find_package(imgui CONFIG REQUIRED)
	find_package(Stb REQUIRED)
	find_package(tinyobjloader CONFIG REQUIRED)
	find_package(Vulkan REQUIRED)

and here:

RayTracingInVulkan/src/CMakeLists.txt

Lines 169 to 171 in 9e4b225

	target_include_directories(${exe_name} PRIVATE . ${Boost_INCLUDE_DIRS} ${glfw3_INCLUDE_DIRS} ${glm_INCLUDE_DIRS} ${STB_INCLUDE_DIRS} ${Vulkan_INCLUDE_DIRS})
	target_link_directories(${exe_name} PRIVATE ${Vulkan_LIBRARY})
	target_link_libraries(${exe_name} PRIVATE ${Boost_LIBRARIES} freetype glfw glm::glm imgui::imgui tinyobjloader::tinyobjloader ${Vulkan_LIBRARIES} ${extra_libs})

Here is a same issue on version 2023.12.26 when I compile the code in CLion IDE, ubuntu 22.04, and the error log is:

CMake Error at CMakeLists.txt:62 (find_package):
  By not providing "FindStb.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Stb", but
  CMake did not find one.

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

    StbConfig.cmake
    stb-config.cmake

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


-- Configuring incomplete, errors occurred!

[Failed to reload]

and I added the following line in CMakeLists.txt ,

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/build/vcpkg.linux/packages/stb_x64-linux/share/stb")

then it worked!

All things go perfectly!
