The issue I have always suffered is that search_group (or related parties)
ignores source files (any specified) if they are not used in the targets.

Here is illustration from one of my C++ headers-only pet projects:

1) I need to collect and structure all headers I want to have listed in
Solution Explorer in Visual Studio:
https://github.com/mloskot/boost-gil-workshop/blob/master/CMakeLists.txt

file(GLOB GIL_HPP "${GIL_DIR}/*.hpp")
file(GLOB GIL_EXT_IO_HPP "${GIL_EXT_IO_DIR}/*.hpp")
file(GLOB GIL_EXT_IO_DETAIL_HPP "${GIL_EXT_IO_DIR}/detail/*.hpp")

# Make single list with all headers for convenience in 2)
if(MSVC)
  list(APPEND GIL_ALL_HPP ${GIL_HPP})
  list(APPEND GIL_ALL_HPP ${GIL_EXT_IO_HPP})
  list(APPEND GIL_ALL_HPP ${GIL_EXT_IO_DETAIL_HPP})
endif()

2) Indicate the headers are used source files:

add_executable(gil_pnm_test gil_pnm_test.cpp ${GIL_ALL_HPP})

3) Assign headers to groups:

https://github.com/mloskot/boost-gil-workshop/blob/master/test/CMakeLists.txt

source_group("Header Files\\gil" FILES ${GIL_HPP})
source_group("Header Files\\gil\\extension\\io_new" FILES ${GIL_EXT_IO_HPP})
source_group("Header Files\\gil\\extension\\io_new\\detail" FILES
${GIL_EXT_IO_DETAIL_HPP})

Has anything changed to make the procedure easier?
