Im using termux and have an error on libflags

[PiotraXc]

Can anyone help?

checking for LIBGFLAGS... no

configure: error: Package requirements (libgflags) were not met:

No package 'libgflags' 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 LIBGFLAGS_CFLAGS
and LIBGFLAGS_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
