[c++] "No rule to make target 'install'"... But Makefile exists

I am running into issues installing a C++ library. The CMake command is successful and generates the Makefile, but it gives a warning:

CMake Warning (dev) at CMakeLists.txt:27 (LINK_DIRECTORIES):
This command specifies the relative path

../usr/local/lib

as a link directory.

Policy CMP0015 is not set: link_directories() treats paths relative to the
source dir.  Run "cmake --help-policy CMP0015" for policy details.  Use the
cmake_policy command to set the policy and suppress this warning.
This warning is for project developers.  Use -Wno-dev to suppress it.

Line 27 in CMakeLists.txt is

Boost_LIBRARY_DIR_DEBUG:PATH=/usr/local/lib

I don't see why this warning would cause me any issues. But when I run make install, I get an error:

make: *** No rule to make target `install'.  Stop.

Any ideas?

I also came across the same error. Here is the fix: If you are using Cmake-GUI:

1. Clean the cache of the loaded libraries in Cmake-GUI File menu.
2. Configure the libraries.
3. Generate the Unix file.

If you missed the 3rd step:

*** No rule to make target `install'. Stop.

error will occur.

I was receiving the same error message, and my issue was that I was not in the correct directory when running the command make install. When I changed to the directory that had my makefile it worked.

So possibly you aren't in the right directory.
