cmake install error

[Marcin Wojdyr]

I get

Install the project...
-- Install configuration: ""
CMake Error at cmake_install.cmake:31 (FILE):
  file INSTALL cannot find
  "/run/mw/cj-build/build-i686-w64-mingw32/libgd-2.1.0-preview/DESTINATIONexamples".

which i suppose is caused by this line:

install(FILES ${top_level_DOCFILES} DESTINATION ${DOC_DIR})

with unset top_level_DOCFILES variable.
