Package input was not found in the pkg-config search path.
Perhaps you should add the directory containing `input.pc'
to the PKG_CONFIG_PATH environment variable
Package 'input', required by 'ecore-x', not found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables E_THUMB_CFLAGS
and E_THUMB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
