Hi,
I’m using ExternalProject, but the documentation does not really reflect what I
am witnessing
I have a Project X which is included through ExternalProject in Project A
Project X has no PREFIX set in its CMakeLists
I include project X like this:
include(ExternalProject)
ExternalProject_Add(x
PREFIX x
URL ${CMAKE_CURRENT_SOURCE_DIR}/externals/x
)
Now according to the documentation the installed files should be available in
the top of the prefix-dir, in this case ${CMAKE_BINARY_DIR}/x/ [installed
files], though I can only see the src dir of ‘x’ and when looking at the output
of the make of ‘x’ I can see its trying to install to default directories in
this case '/usr/local’.
In the documentation, doesn’t the install_dir not mean the same as the install
directory where project ‘x’ will install its files? Because one would think so
because BINARY_DIR does have these semantics.
For reference from the documentation:
The *_DIR options specify directories for the project, with default
directories computed as follows. If the PREFIX option is given to
ExternalProject_Add() or the EP_PREFIX directory property is set, then an
external project is built and installed under the specified prefix:
TMP_DIR = <prefix>/tmp
STAMP_DIR = <prefix>/src/<name>-stamp
DOWNLOAD_DIR = <prefix>/src
SOURCE_DIR = <prefix>/src/<name>
BINARY_DIR = <prefix>/src/<name>-build
INSTALL_DIR = <prefix>
