curl - Imported library from ExternalProject_Add -


i want download , buld curl library sources in cmake project:

... externalproject_add(     curl_external_project     prefix curl     url https://curl.haxx.se/download/curl-7.55.1.tar.gz     configure_command ${cmake_current_binary_dir}/curl/src/curl/configure --prefix=${cmake_current_binary_dir}/curl )  add_library(curl shared imported) set_target_properties(curl properties imported_location ${cmake_current_binary_dir}/curl/lib) set_target_properties(curl properties interface_include_directories ${cmake_current_binary_dir}/curl/include) add_dependencies(curl curl_external_project)  target_link_libraries(${project_name} curl) ...

the problem in configure time ${cmake_current_binary_dir}/curl/include directory doesn't exists, therefore cmake says cmake error in cmakelists.txt: imported target "curl" includes non-existent path.

how include libraries compiled externalproject_add?

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
