I'm trying to get cmake to compile an autoconf external library that comes

works, but I get an error message saying no CMakeLists.txt exists in that
directory.

I figured because BUILD_DIR is set to "make", I wouldn't need a
CMakeLists.txt file in that directory. Anyway, I tried including an empty
one and get a "no rule to make target install", which is closer, but still
not correct as I'm not calling "make install", right?
Here's my root CMakeLists.txt. Is there another argument or something to
get this to work? Why does including "make" give an "install" message? If
I'm doing the whole autoconf workflow, do I need the full set of commands
"configure; make; make install" or is cmake doing some fancy logic?
cmake_minimum_required(VERSION 2.8)
project(ppml)
include(ExternalProject)
ExternalProject_Add(
fftw
DOWNLOAD_COMMAND ""
SOURCE_DIR /home/stratton/Public/ppml/external/fftw-3.3.3
BUILD_COMMAND make
BUILD_IN_SOURCE 1
)
The documentation says
# If SOURCE_DIR is explicitly set to an existing directory the project
# will be built from it.
# Otherwise a download step must be specified using one of the
# DOWNLOAD_COMMAND, [...]
So my guess is you should drop the DOWNLOAD_COMMAND entirely rather than
specifying an empty string for it.
If that doesn't work, there are other alternatives which I know do work.
