Thanks! From that I was able to narrow it to a simple test case:
------------------------------------------------------------------------------
$ cat CMakeLists.txt
cmake_minimum_required(VERSION 3.0)
project(Foo C)
add_subdirectory(A)
add_library(B SHARED empty.c)
install(TARGETS B DESTINATION lib EXPORT FooTargets)
install(EXPORT FooTargets DESTINATION lib/cmake/foo
EXPORT_LINK_INTERFACE_LIBRARIES)
$ cat A/CMakeLists.txt
add_library(A SHARED ../empty.c)
install(TARGETS A DESTINATION lib EXPORT FooTargets)
$ mkdir b ; cd b
$ cmake --version
cmake version 3.5.0-rc1
$ cmake ..
...
Segmentation fault
------------------------------------------------------------------------------
This was likely caused by this change:
cmExportSet: Store a cmGeneratorTarget.
https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=381e7afd#patch6
Here is a fix and a test case:
install(EXPORT): Fix crash on target in another directory
https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=290fb8b9
I've queued this for merge to 'release' for inclusion in 3.5.0-rc2.
Thanks,
-Brad
