CMake Error at CMakeLists.txt:37 (find_package): Could not find a package configuration file provided by "libhydrogen" with any of the following names:

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

I know that the problem is when trying to include libhydrogen, because without this library the code compiled normally. My question is if anyone knows how I can make cmake find this library? It's located in a folder in my project, not in /usr/lib !

the problem is solved. I didn't use the libhydrogen library, I changed it to botan (both for cryptography). However, when compiling I came across the same error. What I did to solve it was to create this Find.cmake with the instructions to compile.

It looked like this:

modules/FindBotan.cmake

find_package(PkgConfig REQUIRED)

if (NOT TARGET Botan::Botan)
  pkg_check_modules(Botan QUIET IMPORTED_TARGET botan)
  if (TARGET PkgConfig::Botan)
    add_library(Botan::Botan ALIAS PkgConfig::Botan)
  endif ()
endif ()

if (NOT TARGET Botan::Botan)
  find_path(Botan_INCLUDE_DIRS NAMES botan/botan.h
            PATH_SUFFIXES botan-2
            DOC "The Botan include directory")

  find_library(Botan_LIBRARIES NAMES botan botan-2
               DOC "The Botan library")

  mark_as_advanced(Botan_INCLUDE_DIRS Botan_LIBRARIES)

  add_library(Botan::Botan IMPORTED UNKNOWN)
  set_target_properties(
    Botan::Botan
    PROPERTIES
    IMPORTED_LOCATION "${Botan_LIBRARIES}"
    INTERFACE_INCLUDE_DIRECTORIES "${Botan_INCLUDE_DIRS}"
  )
endif ()

include(FindPackageHandleStandardArgs)
find_package_handle_standard_args(
  Botan
  REQUIRED_VARS Botan_LIBRARIES Botan_INCLUDE_DIRS
)

CmakeLists looks like this:
