header include errors when using FetchContent_Declare

[willie]

I was using vcpkg, but it's stuck at 1.9.1, so I thought I would use FetchContent_Declare from cmake to pull my OpenTelemetry dependency in. I've probably made a rookie mistake, but here's what I put in my CMakeLists.txt file (I set options to mirror to as best as I could figure from this repo and vcpkg):

SET(BUILD_TESTING OFF CACHE BOOL "BUILD_TESTING" FORCE)
SET(WITH_EXAMPLES OFF CACHE BOOL "WITH_EXAMPLES" FORCE)
SET(WITH_OTLP_HTTP ON CACHE BOOL "WITH_OTLP_HTTP" FORCE)
SET(OPENTELEMETRY_INSTALL ON CACHE BOOL "OPENTELEMETRY_INSTALL" FORCE)
SET(WITH_ABSEIL ON CACHE BOOL "WITH_ABSEIL" FORCE)

FetchContent_Declare(
	opentelemetry-cpp
	GIT_REPOSITORY https://github.com/open-telemetry/opentelemetry-cpp.git
	GIT_TAG        v1.11.0
)
FetchContent_MakeAvailable(opentelemetry-cpp)
target_include_directories(${CMAKE_PROJECT_NAME} PRIVATE opentelemetry-cpp)
target_include_directories(${CMAKE_PROJECT_NAME} PRIVATE ${OPENTELEMETRY_CPP_INCLUDE_DIRS})

target_link_libraries(${CMAKE_PROJECT_NAME} PRIVATE ${OPENTELEMETRY_CPP_LIBRARIES})

when I do this and build, I get:

fatal error: 'opentelemetry/exporters/otlp/otlp_http_exporter_factory.h' file not found
#include "opentelemetry/exporters/otlp/otlp_http_exporter_factory.h"

and

fatal error: 'opentelemetry/trace/provider.h' file not found
#include <opentelemetry/trace/provider.h>

Any suggestions how to resolve this? How are people building static linked apps with OpenTelemetry?

How are people building static linked apps with OpenTelemetry?

This should work. Can you share the build logs ?

I was using vcpkg, but it's stuck at 1.9.1

tagging @ThomsonTan for vcpkg upgrade.

I did file an issue on the vcpkg repo. microsoft/vcpkg#33772 (build log to come, I made some progress)

I was able to get past the header issues by specifying some additional parameters, but I have linker errors now, attached! (Thanks for the help)

Do you have any further suggestions?
